Wells Fargo promptly reassured its customers after finding itself the victim of a cyber attack yesterday. “The vast majority of customers are not impacted and customer information remains safe," said Bridget Braxton, a spokeswoman for the fourth-largest U.S. bank by assets. Being in the position to quickly – and credibly – provide such reassurance can make all the difference in terms of fallout from a breach. Data breaches and cyber attacks happen every day to businesses large and small. Be sure that you have an incident response plan in place before one happens to yours.
